The object of the'present invention is to i provide a window structure,preferably formed of rolled sheet metal elements, and in which.glass-carrying frames are employed mounted in the sashes and capable oflateral movement for the purpose of giving ventilation and also makingthe outer sides of the panes accessible within the room for the purposeof cleaning. A further and important object isto provide a structure ofrelatively simple character in which the glass-carryin frames will bemaintained wherever place In the accompanying drawings Figure 1 is aperspective view of the preferred embodiment of the invention andshowing the glass-carrying frames in various positions.

' Figures 3 and 4 are cross pivot and holding Figure 2 is a verticalsectional view through the window structure with the sashes and transomclosed. V

Figure 5 is a perspective view of oneof the devices.

In the embodlment disclosed a window frame is provided that isrefer-ably formed of sheet metal; and inclu es a sill member 6 havinganupstanding abutment rib 7 for the lower sash. The sides of the frameare in the form of boxes 8, in which'the usual weights indicatedat 9 inFigure 3. reci rocate. The sides include plates 10 locate on' the innersides of the boxes 8 and these plates ide slots 11. They arehavelongitudinal furthermore provi ed with channeled members 12 that servealso as guides. Inthe present structure a tubular rail formed of sheetmetal sections and designated 13 divides the 4 frame into an uppertransom opening14 and a lowerwindow opening 15. A transom is shown at'16, saidtransom being pivoted at its lower end as illustrated at 17wher'eby it may be swung inwardly. A latch 18 serves to hold. thetransom in its closed position. In the window opening 15 arecooperatingvertically sliding sashes Hand 20. As these sashesaresubstantially alike in structure, a description of one it is believed besuflicientfor both, the material differences being later pointed out.

' lated to the sash frame that ures 3 and 4 that the outstandiii flanges22 travel in the 'de channels 12. ixedto the outer sides 0 the bodystrips 21 of the stiles are angle bars or strips 24, the outstan flangesof which travel in the. guide slots 11 of t e plate 10. It will thus beevident that the sashes are guided vertically in the window frame. Thebottom rail of the upper sash has its upstanding flange 22 inset at anin'clination, as shownv at 25, and the top rail of the lower sash hassecured u on it a strip 26 provided with a downturned'mclined rtion 27that overlies the portion 25. sashes are closed (see F re 2) turnedflange 23 of the ttom. rail of the lower sash 20 depends over and alondo the upstanding portlon 7 of the sill 6.

angle bar.28 t at enters a groove 29 formed by the downturnedterminal'flanges 30 of the main frame rail 13. Thus 'interfittingportions are provided between the two. sashes and between the two sashesand the window i frame, that serve to air and water.

- In each of the sashes 19 and 20 is mounted a laterally movableglass-carrying frame, and as the frames in both instances are the same,a description of one will do for both. Each sash-carrying frame consistsof substantially Z-shaped bars or strips comgrisi portion 31 with anoutstan ing flange 32 along its inner edge and an inset flange 33 alongits outer edge. The latter flange is bent prevent the entrance ofreceiving channel 35. The glass pane is shown an angle strip 37 placedbehind t 0 las an secured to the body portion 31. t will be noted thatthe glass-carrying frame is so rethe former abut the flange 23 of thelatter and that the flange 32 ofsaid lass-carryingframe abuts the flange22 of t 0 each frame when inwardly as shown at'34 to provide a puttytheglass-carrying frame is in its closed position orfitted within the sashframe.

The glass-carrying frame has pivoted to its stiles and as shown at 38the lower ends of .links 39, the pivots 38 being preferably'locatedbelow the centers of said stiles. The upper ends of the links 39 arepivoted to the inner sides of the upper ends of the sashcarrying frames,as shown at 40. The lower end of the glass-carrying frame has a slidingpivotal mounting in the sash frame. To this end there are secured to theinner sides of the lower portions of the stiles of said sash framesvertical channel bars 41. The lower rails of the glass-carrying framehave secured thereto angle bars 42 which form with the flanges 32 achannel 43. In this channel are secured spring-pressed plungers (seeFigure 5 for the detail thereof). A U-shaped frame '44 is secured in thechannel 43, thus providing spaced downturned ears 45.and in said ears isa reciprocatory plunger 46 having a cylindrical head 47 that engages inone of the guide channel bars 41. On the shank of the plunger 46 isacoiled spring 48 that abuts against the rear ear and against a shoulder49 formed on the shank. .The spring thus urges the plunger outwardlyand; causes the free end of its head to frictionally bear withconsiderable pressure against the bottom .of the channel 'guideway 41.There being two of these plungers, it will be evident that they projectfrom the opposite lower corners of the sash-carrying frame andconstitute not only pivots on which the said frame swings,-

but also act as sliding frictional bearing members in the sash frame. Itwill be noted by 1 referenceto Figure 2 that when the glasscarryingframe is in its closed position; the

lower flange 32 depends on the outer side of and against the upstandingflange 22 of the sash frame and that the depending flange 42 oftheglass-carrying-frame depends on the outer side and against the flange 23of the sash frame. A'tight joint is thus obtained. The upper end of theglass-carrying frame can be secured to the sash frame by any suitablemeans, as for instance a rotary latch 50 mounted on the upper end of theglass-carrying frame and having a nib 51 that inter-.

locks with the upperrail of the sash frame. A suitable detachable handleshown at 52 in Figure 1 can be used for turning this latch.

' With this construction, when the sash carrying frames are closed andlocked. both upper and lower sashes may be raised or lowered in theusual manner. If it is desired to open either or both of the windows forventilating purposes and without raising the sashes, it is onlynecessarv to unlock and draw the glass-carryingframes inwardlv'. Thiscauses the upper ends of said frames to swing inwardly, while the lowerrails turn on the pivot axes of the heads 37 and thus the flanges 22 and23 and rise above the same. The glass-carrying frames can be positionedas desired and as indicated in Figure 1, their positions beingmaintained by the spring plungers frictionally engaging the bottoms ofthe channel pieces 41 and holding the'frames against accidentalmovement.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in \the art without flanges 32 and 42 will swing away fromthe further description and it will be understood rying frame, guidewayon the "stiles of the sashframe, and spring-pressed plungers locatedlongitudinally of and housed in the ends of the channel of saidchanneled rail of the glass-carrying frame and slidablyextending throughthe open end of the channel and engaged in the guideways of the sashframes stiles.

' 2. In a window structure, the combination with a sash frame includinga rail having spaced flanges, of a glass-carrying frame including a railhaving spaced flanges that slidably overlap the flanges of the sashrail, said flanges of the rail of the glass-carrying frame forming anopenended channel between them, links pivoted to the sash frame and tothe glass-carrying frame, guideways on the .st'iles of the vsash frameand springpressed plungers located longitudinally of and housed in thechannel of said rail of the glass-carrying frame and having their endsextending through the open ends of the channel and slidably engaged inthe guideways of the sash frames stiles.

3. In a window structure, the combination with a window frame, of a sashframe ,slidouter sides of the flanges of the said sash frame rail, linkspivoted to the upper por tions of the stiles of the sash frame-and tointermediateportions of the stiles of the glass-carrying frame, andspring-pressed plungers located longitudinally of and in the channel ofthe rail of the glass-carrying frame and projecting into andfrictionally engaging the guide channels ofthe stiles of J the sashframe.

4. In a window structure, the combination with a sash frame having astile provided with an inset outer flange and a gnideway behind theflange, a glass carrying frame having a stile that abuts against theflange and having an inner outstanding flange that abuts the sash stile,forming a boxing for the guideway, said sash carrying frame havingachanneled cross rail, and a spring pressed plunger locatedlongitudinally of and housed in the channel of the rail and having ahead slidable in the guideway of the sash stile.

5. In a window structure, the combination with a sash frame having astile provided with an inset outer flange and a longitudinal gnidewaybehind the flange at one end of the stile, a glass carrying frame havinga stile that abuts against the flange and having an inner outstandingflange that abuts the sash stile forming a boxing for the guideway, alink pivoted to both stiles at one end of the guideway and enclosed bythe flanges of the stiles, said sash carrying frame having an open-endedchanneled rail, and a .30 spring-pressed plunger housed in the channelof the rail and having a head extended through the open end and slidablein the guideway of the sash stile.
